Took the first step towards building my shop

It has been a lot of years since I have found the bulk deals I used to find but at one time I bought a freight tanker load of bulk Portland for ten dollars a ton at a derailment site. I hired 3 dry bulk vacuum tankers to pump it out of the freight tanker. However stupid me, I sold the cement to a batch plant for a huge profit, instead of thinking that 20 years later I might need it for my own slab

It would probably be a solid chunk if you stored it that long, but maybe you have some water vapor proof storage vessels. It screams to be hydrated. I've learned that even the bags that have a plastic film between the paper structural sheets, let moister in. Really disappointing when you find the 3 bags you got on sale are solid. And absolutely do not store on concrete as that exudes moister, and keeps the cement below dew point (the lesson was delivered this way). So I shall see in a few weeks if storing the left over bags in a dry wall mud pails with a sealed lid keeps it dry. That was 3 years ago. I have a critical repair task of my storage building, that is 3 feet from a retaining wall, about 3 feet high. The wall is tilting outward and letting the sand below the building slump along with this. The building is on a concrete slab, made from that crappy limestone aggregate, that I mixed myself. The freeze thaw is making that slab punky. Soft enough that a ground hog (marmot) dug through it 3 years ago, and undermined the building and filled the floor area it could with 2 feet of the earth from below the building. I hate ground hogs, and they are my enemy. And as this building is above the surrounding area this attracts them for a winter home that is dry. They have some instinct that knows the winter melt will fill a den if it can't drain out. I accidentally made a hill for them. They hibernate in our climate.
